WATCH MOVEMENT Filed June 25, 1929 Patented Feb. 16, 1932 PATENT OFFICE ROGER MOERI, OF ST. IMIER, SWITZERLAND WATCH MOVEMENT Application led June 26, 1929, Serial No. 373,837, and in Switzerland May 16, 1929.

The present invention relates to a watch regulator which is made adjustable by means of a pinion fixed onto a regulating disk, this disk being mounted slidably in a slot arranged in line with the regulators center and combined with a spring so as to keep the pinion in constant and close contact with the regulator and to correct the distance between the centers of pinion and the pivot of the regulator.

The Figure l is a plan view of a cock carrying a regulator according to the present invention and the Figure 2 is a longitudinal section on line II-II of the Figure l.

The regulator 1 is held pivotally fast on the plate 2 of the cock by means of a disk 2. The tail 11 of the regulator carries toothed segment 3 engaged with a pinion 4. This pinion has a pivot pin 5 made of the same piece with it and engaged in a slot 6 of the plate. The

slot shown in Fig. 2 is arranged in line with the regulators pivot and allows therefor the displacement of the pinion 4 from or towards the pivot of the toothed segment 3. A regulating disk 7 pressed fast over the pivot pin 5 of the pinion allows to turn this latter when the regulator is to be adjusted. The disk can be turned by means of a pointed instrument engaged into holes 8 provided near the periphery of the disk.

The true gearing between pinion 4 and segment 3 is assured by a spring 9 having two wings 9 bearing on the periphery of the disk 7 The two gears are kept in constant and close engagement by the spring 9 which is supported by the border of recess 11 forming the lodging of this spring. This arrangement allows to avoid all play between the gears and to correct also the distance between the centers o of pinion and regulator. Besides the pressure of the two wings 9 on the periphery of the disk 7 prevents this latter from turning by itself and leaves still all liberty for turning said disk by hand when it is desired to adjust it.

Disk 7 and spring 9 are both kept down in the recess 11 by means of the same screw 10.

What I claim is:

In a watch movement and in combination a cock plate having a pivot hole and having a recessed portion with a slot therein in line with the center of said pivot hole, a regulator mounted rotatably on said cock plate and provided with a tail carrying a toothed segment, a regulating disk lodged within said recessed portion of the plate and having holes near its periphery as turning means for its adjustment, a pinion fixed to said regulating disk meshing with the toothed segment and having a pivot pin extending into said slot, a two winged spring in said recess and bearing on the periphery of the disk in the direction of the pivot hole of the plate so as to maintain the true engagement between pinion and segment and a screw retaining the spring and disk in said recess.

In testimony whereof I aix my signature.

ROGER MOERI.
